feat: Added Prometheus metrics support and optimized the homepage interface.

Added the prometheus/client_golang dependency to support metrics collection, and refactored the proxy processor's homepage.
It uses modern CSS styles and responsive design, and adds code copy functionality.
BREAKING CHANGE: Removed session selection-related methods and the large buffer feature of the buffer pool in TCP connection groups.
